Example Embodiments

The following detailed description refers to the accompanying drawings.Wherever possible, the same reference numbers are used in the drawingsand the following description to refer to the same or similar elements.While embodiments of the disclosure may be described, modifications,adaptations, and other implementations are possible. For example,substitutions, additions, or modifications may be made to the elementsillustrated in the drawings, and the methods described herein may bemodified by substituting, reordering, or adding stages to the disclosedmethods. Accordingly, the following detailed description does not limitthe disclosure. Instead, the proper scope of the disclosure is definedby the appended claims.

FIG. 1 shows an operating environment 100 for a coupled cable. As shownin FIG. 1 , operating environment 100 may include a system 105 forproviding energy and a control signal using a coupled power and controlcable. Operating environment 100 may comprise, but is not limited to, ahome, a business, a commercial space, an industrial space, or anysimilar area. Operating environment 100 may comprise an electrical panel110 fed by a transformer 115. Electrical panel 110 may include circuitbreakers used to feed circuits out of electrical panel 110. Once suchcircuit may be used to feed system 105. Transformer 115 may be operatedby an electric utility entity and may step voltage down from a levelused by the electric utility entity to a level usable by operatingenvironment 100.

System 105 may comprise a fixture 120 connected to a control device 125via a coupled cable 130. Control device 125 may comprise a switch 135and a control circuit 140. Electrical energy may be fed to controldevice 125 from panel 110. Fixture 120 may comprise any type device thatconsumes energy and can be controlled. For example, fixture 120 maycomprise, but is not limited to, a light such as a Light Emitting Diode(LED) light or a florescent light. Switch 135 may be configured tointerrupt the supply of electrical energy to fixture 120. For example,when switch 135 is closed, electrical energy may be supplied to controldevice 125 and fixture 120 from electrical panel 110. However, whenswitch 135 is open, the electrical energy supplied to control device 125and fixture 120 from electrical panel 110 may be interrupted.

Control circuit 140 may comprise any device used to control fixture 120.For example, when fixture 120 comprises a light such as an LED light,control circuit 140 may comprise, but is not limited to, a dimmer forthe LED light. The dimmer may comprise, for example, a potentiometer andmay be configured to supply a control signal that may comprise a voltagesignal between 0V and 10V. As the voltage of the control signal fromcontrol circuit 140 changes (e.g., increases), the LED light may supplya corresponding change (e.g., higher light intensity) in response.

FIGS. 2A, 2B, and 2C show coupled cable 130 in more detail. As shown inFIG. 2A, coupled cable 130 may comprise a power cable 205, a controlcable 210, and an overall jacket 215. Overall jacket 215 may comprisecomplementary valleys 220, a connector portion 225, and a stripe 230. Asshown in FIG. 2B, coupled cable 130 may have a first end 235 and asecond end 240.

Power cable 205 may comprise a power cable jacket 245, a power cablefirst conductor 250, a power cable second conductor 255, and a powercable ground wire 260. Power cable 205 may comprise a non-metallic (NM)sheathed cable that maybe used, for example, for both exposed andconcealed work in normally dry locations at temperatures not to exceed90° C. (with ampacity limited to that for 60° C. conductors) asspecified in the National Electrical Code (NEC). Power cable 205 maycomprise a Class 1 remote-control and signaling circuit cable as definedby the NEC. Class 1 cables typically operate at 120V, but the NECpermits them to operate at up to 600V.

Power cable first conductor 250 may comprise, but is not limited to,American Wire Gage (AWG) 12 Thermoplastic High Heat-resistantNylon-coated (THHN) copper wire with black insulation. Power cablesecond conductor 255 may comprise, but is not limited to, AWG 12 THHNcopper wire with white insulation. And power cable ground wire 260 maycomprise, but is not limited to, an AWG 12 bare copper wire. Paperfillers may be placed inside power cable jacket 245 between power cablefirst conductor 250, power cable second conductor 255, and power cableground wire 260. The aforementioned wires are not limited to solidcopper and may be stranded or may comprise any conductive metal ornon-metal material.

Control cable 210 may comprise a control cable jacket 265, a controlcable first conductor 270, and a control cable second conductor 275.Control cable 210 may not include a ground wire. Control cable firstconductor 270 may comprise, but is not limited to, an AWG 16 TFN copperwire with grey insulation. Control cable second conductor 275 maycomprise, but is not limited to, an AWG 16 TFN copper wire with purpleinsulation. The aforementioned wires are not limited to solid copper andmay be stranded or may comprise any conductive metal or non-metalmaterial.

Control cable 210 may comprise a Class 1 remote-control and signalingcircuit cable as defined by the NEC. Class 1 cables typically operate at120V, but the NEC permits them to operate at up to 600V. Althoughcontrol cable 210 may only be operated within Class 2 voltage andcurrent level limits, control cable 210 may be insulated and otherwisecomprise a Class 1 cable. For example, Class 2 circuits typicallyinclude wiring for low-energy (100VA or less), low-voltage (under 30V)loads such as low-voltage lighting, thermostats, PLCs, security systems,and limited-energy voice, intercom, sound, and public address systems.Class 2 circuits may protect against electrical fires by limiting thepower to 100VA for circuits that operate at 30V or less, and 0.5VA forcircuits between 30V and 150V. Electric shock may be protected againstby limiting the current of the circuit to 5 mA or less for circuitsbetween 30V and 150V.

Overall jacket 215 may cover both power cable 205 and control cable 210.As stated above, power cable 205 may comprise an NEC Class 1 cable.Because power cable 205 and control cable 210 are included under thesame overall jacket 215, control cable 210 may also comprise an NECClass 1 cable even though control cable 210 may only be operated withinNEC Class 2 voltage and current level limits.

Coupled cable 130 may include power cable 205 and control cable 210 in aside-by-side configuration. For example, as shown in FIG. 2A, an axismay pass through the conductors of both power cable 205 and controlcable 210. In addition, overall jacket 215 may comprise complementaryvalleys 220 and connector portion 225 that may aid in tearing powercable 205 and control cable 210 apart. For example, an operator maygrasp power cable 205 with the fingers of one hand and grasp controlcable 210 with the fingers of the other hand and pull the two apartalong connector portion 225. Stripe 230 may be included in overalljacket 215 to indicate (e.g., to an operator) which side of coupledcable 130 may comprise power cable 205 and which side may comprisecontrol cable 210. The example shown in FIG. 2A shows stripe 230oncontrol cable 210 side of coupled cable 130, however it may be includedon power cable 205 side of coupled cable 130 instead. Notwithstanding,an indicator may be used with embodiments of the disclosure to indicatewhich side of coupled cable 130 includes power cable 205 and which sideincludes control cable 210.

FIG. 3 is a flow chart setting forth the general stages involved in amethod 300 consistent with embodiments of the disclosure for providing acoupled power and control cable system. Method 300 may be implementedusing coupled cable 130 as described in more detail above with respectto FIG. 1 and FIGS. 2A, 2B, and 2C. Ways to implement the stages ofmethod 300 will be described in greater detail below.

Method 300 may begin at starting block 305 and proceed to stage 310where coupled cable 130 may be received by an operator. For example, asdescribed above, coupled cable 130 may comprise overall jacket 215beneath which power cable 205 and a control cable 210 are disposed.Overall jacket may comprise complementary valleys 220 and connectorportion 225 disposed between power cable 205 and control cable 210.Overall jacket may have a stripe on a portion of overall jacket 215under which control cable 210 is disposed. Power cable 205 may be Class1 and control cable 210 may be Class 1. Although control cable 210 mayonly be operated within Class 2 voltage and current level limits,control cable 210 may be insulated and otherwise comprise a Class 1cable because overall jacket 215 may cover both power cable 205 andcontrol cable 210.

From stage 310, where coupled cable 130 is received by the operator,method 300 may advance to stage 320 where the operator may select, basedupon stripe 230 on coupled cable 130, control cable 210 from coupledcable 130. Stripe 230 may be included in overall jacket 215 to indicateto the operator which side of coupled cable 130 may comprise power cable205 and which side may comprise control cable 210. The example shown inFIG. 2A shows stripe 230 on control cable 210 side of coupled cable 130,however it may be included on power cable 205 side of coupled cable 130instead. Notwithstanding, an indicator may be used with embodiments ofthe disclosure to indicate which side of coupled cable 130 includespower cable 205 and which side includes control cable 210.

Once the operator selects, based upon stripe 230 on coupled cable 130,control cable 210 from coupled cable 130 in stage 320, method 300 maycontinue to stage 330 where the operator may connect first end 235 ofselected control cable 210 to control circuit 140 of control device 125.For example, the operator may grasp power cable 205 with the fingers ofone hand and grasp control cable 210 with the fingers of the other handand pull the two apart along connector portion 225 for a small length ofcoupled cable 130 at first end 235. The operator may then connect theseparated power cable 205 at first end 235 to switch 135 and theseparated control cable 210 at first end 235 to control circuit 140.

After the operator connects first end 235 of selected control cable 210to control circuit 140 of control device 125 in stage 330, method 300may proceed to stage 340 where the operator may connect second end 240of selected control cable 210 to fixture 120. For example, the operatormay grasp power cable 205 with the fingers of one hand and grasp controlcable 210 with the fingers of the other hand and pull the two apartalong connector portion 225 for a small length of coupled cable 130 atsecond end 240. The operator may then connect the separated power cable205 at second end 240 to fixture 120 and the separated control cable 210at second end 240 to fixture 120.

Prior to connecting first end 235 of coupled cable 130 to control device125 or connecting second end 240 of coupled cable 130 to fixture 120,the operator may first pull coupled cable 130 in system 105 betweenfixture 120 and control device 125. Because overall jacket 215 may coverboth power cable 205 and control cable 210, the cable pull is simplifiedbecause only one cable (i.e., coupled cable 130) need be pulled betweenfixture 120 and control device 125. With conventional systems, twocables rather than one would need to be pulled. Embodiments of thedisclosure provide an improvement by simplifying this cable pull.Furthermore, because power cable 205 and control cable 210 are under thesame overall jacket 215, there may be no confusion to the operator as towhich power cable corresponds to which control cable when multiplefixtures and multiple control devices are employed in system 105 becausecorresponding power cables and control cables are attached to oneanother. Once operator connects second end 240 of selected control cable210 to fixture 120 in stage 340, method 300 may then end at stage 350.

FIG. 4 is a flow chart setting forth the general stages involved in amethod 400 consistent with embodiments of the disclosure for providingservice using a coupled power and control cable system. Method 400 maybe implemented using coupled cable 130 as described in more detail belowwith respect to FIG. 1 and FIGS. 2A, 2B, and 2C. Ways to implement thestages of method 400 will be described in greater detail below.

Method 400 may begin at starting block 405 and proceed to stage 410where coupled cable 130 may be provided between fixture 120 and controldevice 125. Control device 125 may comprise switch 135 and controlcircuit 140. For example, electrical energy may be fed to control device125 from panel 110.

From stage 410, where coupled cable 130 may be provided between fixture120 and control device 125, method 400 may advance to stage 420 whereenergy may be provided to fixture 120 from switch 135. For example,switch 135 maybe configured to interrupt the supply of electrical energyto fixture 120. When switch 135 is closed, for example, energy may besupplied to control device 125 and fixture 120 from electrical panel110. However, when switch 135 is open, the energy supplied to controldevice 125 and fixture 120 from electrical panel 110 may be interrupted.

After energy is provided to fixture 120 from switch 135 in stage 420,method 400 may proceed to stage 430 where a control signal may beprovided to fixture 120 from control circuit 140. The control signal maycomprise a voltage level between a first voltage value and a secondvoltage value. The voltage level may not exceed a maximum valuecorresponding to Class 2. For example, control circuit 140 may compriseany device used to control fixture 120. When fixture 120 comprises anLED light, for example, control circuit 140 may comprise a dimmer forthe LED light. The dimmer may comprise a potentiometer and may beconfigured to supply a control signal that may comprise a voltage signalbetween 0V (e.g., first voltage value) and 10V (second voltage value).As the voltage of the control signal increases, the LED light may supplya corresponding higher light intensity. Power cable 205 may be Class 1and control cable 210 may be Class 1. Although control cable 210 mayonly be operated within Class 2 voltage and current level limits,control cable 210 may be insulated and otherwise comprise a Class 1cable. Once control signal is provided to fixture 120 from controlcircuit 140 in stage 430, method 400 may then end at stage 440.

In addition, overall jacket215 may comprise complementary valleys 220 and connector portion 225that may aid in tearing power cable 205 and control cable 210 apart. Forexample, an operator may grasp power cable 205 with the fingers of onehand and grasp control cable 210 with the fingers of the other hand andpull the two apart along connector portion 225.

FIG. 5B shows connector portion 225 in greater detail. As shown in FIG.5B, connector portion 225 may comprise a webbing disposed within overalljacket 215. The webbing may comprise a webbing first portion 505protruding from overall jacket 215 on the power cable 205 side ofcoupled cable 130 and a webbing second portion 510 protruding fromoverall jacket 215 on the control cable 210 side of coupled cable 130. Afirst webbing valley 515 and an opposing second webbing valley 520 maybe disposed between webbing first portion 505 and webbing second portion510. First webbing valley 515 and second webbing valley 520 may be “V”shaped. Notwithstanding, first webbing valley 515 and second webbingvalley 520 may comprise any shape. As stated above, an operator maygrasp power cable 205 with the fingers of one hand and grasp controlcable 210 with the fingers of the other hand and pull (e.g., tear) thetwo apart along connector portion 225.

Connector portion 225, comprising the webbing that may include firstwebbing valley 515 and opposing second webbing valley 520, may aid inthis pulling or tearing apart of connector portion 225. For example,power cable 205 and control cable 210 may separate along the opposingfirst webbing valley 515 and second webbing valley 520 during thepulling and tearing process. Accordingly, the opposing first webbingvalley 515 and second webbing valley 520 may facility in separatingpower cable 205 and control cable 210.
